Defeated Darwin in 45 hours... is that possible?

The play time for the Darwin defeat video I posted on the Nyan-ko Great War playpick field is showing 45 hours. I played more on my old account, so the time on my current account is probably around 45 hours... but it's funny how the current display makes it look like I'm a hardcore player who beat Darwin in 45 hours. Are there any legit players out there who can clear content to this extent in just 45 hours?
